If continuing with school does not help you with your job prospects, then I would consider quitting. However, if the degree makes you more marketable, then you should continue and try to finish.
I thought about going to school again too. However, I don't feel up to it and don't want to incur a debt. I think going to school is not easy for someone with an illness like mine. I am also old. I already have two degrees. I am not earning money in the fields I studied though. Thus, I think academics and job experience are sometimes not related. I think job experience is more important than education sometimes. But, I'm just a teacher and really don't know. I like my current job and am hoping to do well. I also hope the company promotes me if I'm good. But, I'm old so don't expect too much.
